Summary

The 2012 mid-year population estimate for West Sussex was 815,100

This was a 0.8% increase from the 2011 mid-year estimate, which is an
increase of 6,200 people.

This is similar to the percentage change seen for the South East but
slightly higher than the 0.7% change for England. There were 53.5million
people in England in 2012, 53.1 million in 2011.

The number of older people continues to increase faster than the overall
population change. Between 2011 and 2012, there was a 3.8% increase in
older people aged 65 years and over, which is higher than the 0.9%
increase in the 0-19 years age group and the 0.3% decrease in the 20-64
years age group.

The population increase in West Sussex was accounted for by natural
change (600 more births than deaths) and more significantly, by inward
migration of 5,600 people into the county.

Migration patterns show that there is more internal migration (from other
areas in the UK) into the county than international migration. More than
90% of migration into the county was internal migration. This is seen for
all districts apart for Crawley where net international migration was higher
than net internal migration.

Adur, Arun and Crawley had the highest population increase between
2011 and 2012 while Chichester and Horsham had the lowest population
increase (0.4% and 0.5% respectively).

Population increase in Adur, Arun and Chichester were caused entirely by
inward migration as there were higher number of deaths than births in
these districts.
